Description

Device for sealing at least one door leaf of a rail vehicle and rail vehicle

Technical Field

The invention relates to a device for sealing at least one door leaf of a rail vehicle, a rail vehicle and a method for sealing a sliding door.

Background

Sliding doors are preferably used in rail vehicles. The sliding door, due to its design, runs along at least one guide rail in the opening direction or in the closing direction. Abrasive seals may be used for sealing along the rail.

Disclosure of Invention

The present invention is based on the object of providing an improved device for sealing at least one door leaf of a rail vehicle, an improved rail vehicle and an improved method for sealing a sliding door.

According to the invention, this object is achieved by an apparatus for sealing at least one door leaf of a rail vehicle, a rail vehicle and a method for sealing a sliding door having the features of the invention.

A device for sealing at least one door leaf of a rail vehicle is proposed, wherein the device has at least one displacement device which is designed to move the door leaf in the z direction of the rail vehicle in the region of a closed position in order to press a sealing element of the door leaf against a mating sealing element of a door frame of the rail vehicle.

Wear of the seal in sliding doors or swing-sliding doors can be avoided to a maximum extent when the door leaf of the sliding door is not in contact with the seal during closing and is only in contact with the seal as close as possible to the closed position. This can be achieved by a vertical movement of the door leaf. The door leaf can be moved in the closing direction by means of a guide system. In order to additionally achieve an improved thermal insulation and additionally or alternatively an improved sound insulation, a lifting device, also referred to as a lifting device, can be used, by means of which the door leaf can additionally be moved in the vertical direction, so that a vertical movement can be carried out. The lifting device can be designed as a component of the guide system or as a separate device, also in one embodiment as an attachable device. Thus, not only the individual lifting device but also the components of the guide system or the entire guide system can be understood as a device for sealing according to different embodiments.

The door leaf can be, for example, a sliding door leaf or a swinging sliding door leaf. According to one embodiment, a modularization is provided. Thus, according to one embodiment, the guiding system for the door leaf can be equipped with a lifting device without change or without substantial change. The lifting device can therefore also be designed as a unit that can be retrofitted afterwards. Advantageously, therefore, the customer can choose whether he wants a guide system "only" for opening and closing the door or also a guide system with improved sound or thermal insulation by including lifting equipment. Advantageously, this option can also be added afterwards. The device for sealing may thus comprise at least one attachable component which can be installed into an existing door system in order to enable the door system to move in a vertical direction and thereby enable improved sound and/or heat protection.

The displacement device can be designed as an active component which is designed to move the door leaf in response to a movement signal.

The moving means may also be configured to move the door leaf in an x-direction of the rail vehicle to move the door leaf between the closed position and the open position. The device for sealing may thus comprise other functions of the guiding system or constitute the guiding system itself.

The displacement device can be designed as a passive component which is designed to execute a movement of the door leaf in the z direction by means of a movement of the door leaf in the x direction.

The moving device may have at least one rocker with a guide arm that can be rotated about a pivot point. Preferably, the pivot point can be coupled to a support roller unit which can be moved linearly along an at least partially linear support rail. The guide arm can be supported, for example, via a guide roller unit which can be moved along the guide track or can be supported on the guide track. The rocker can have a fastening point for the door leaf.

According to one embodiment, the rocker has a first guide arm and a second guide arm. The first guide arm can have a first fastening point, at which a first support roller unit for guiding the first guide arm along the guide track is arranged. The second guide arm may have a second fixing point on which a second supporting roller unit for guiding the second guide arm along the guide rail is provided. The pivot point may be coupled to the door leaf and disposed between the first and second fixed points. Points such as points of rotation or points of fixation can also be understood as positions or points on the rocker, for example, or as through openings for receiving the shaft or the shaft part, for example, or as center points of such through openings. The arrangement of the pivot point between the fastening points can mean that the pivot point can be arranged between the fastening points in the x direction, i.e. parallel to the longitudinal axis of the vehicle, wherein a misalignment in the z direction, i.e. parallel to the vertical axis of the vehicle, can occur.

The guide track may have a linear guide surface and a connecting link (Kulisse). The attachment link may be angled relative to the guide surface. The connecting link can be used, for example, as a guide element for guiding the roller unit. By means of the connecting link, the guide roller unit can be deflected out of the plane of the guide surface onto the trajectory.

The guide rail can be formed by a bearing rail or a straight section of a bearing rail. The connecting element can be connected to the mounting rail in a stationary manner. For example, the attachment links may be threaded. The connection links can be simply placed or fixed by means of a threaded connection. For example, the connecting element can be a wedge placed on the support rail.

The guide rail may be constituted by the support rail. The guide surface and/or the connecting element can be designed as a recess in the support rail. For example, the guide rail and/or the connecting element can be milled into the mounting rail. The rocker arm can be positioned accurately by milling.

The transition from the guide surface to the connecting link can be arranged less than 200mm, for example also less than 120mm or less than 80 mm, before the closed position of the door leaf. By this short distance, a small grinding displacement between the seals can be achieved.

The first supporting roller unit may have a first supporting roller having a guide groove for guiding the first supporting roller along a straight guide surface. The second support roller unit may have at least one second support roller having a guide groove for guiding the second support roller unit along a linear guide surface and a connecting link surface for guiding the second support roller unit along the connecting link. The movement track can be constructed as a monorail or as a double track. In a two-rail configuration, the connecting link may be arranged parallel to a section of the straight guide surface. If the first bearing roller does not have a connecting link surface, the first bearing roller can be guided further on the mentioned section of the straight guide surface next to the connecting link, while the second bearing roller is guided on the connecting link on the basis of its connecting link surface.

The fixed point may have a travel of less than 15 mm. A small stroke is sufficient to separate the seals.

The carrying arm of the rocker between the pivot point and the fixing point can be shorter than the guide arm. The forces acting on the support roller unit and the guide roller unit can be reduced by the intermediate position of the fastening point.

The pivot point may be disposed between the fixed point and the guide arm. By means of the fastening point at the free end, the support roller unit can be loaded in the opposite direction to the guide roller unit. The guide arm thus at least partially encloses the guide rail.

The support rail may have a convex support profile. The support roller unit may have at least one support roller with a concave roller profile. The bearing profile may be at least partially surrounded by the roller profile. By providing the rollers and the guide rails with profiled profiles, a good lateral guidance for the door leaf is produced. The additional lateral guide can therefore be dispensed with.

The guide system may have a door leaf support, which is rotatably mounted in a fastening point. The door leaf support can be connected to the rocker via a web. By means of the door leaf bracket, the door leaf can be adjusted with respect to its position.

The door leaf carrier can be rotatably mounted in the further rocker. The door leaf can be prevented from vibrating by the two rockers.

Furthermore, a rail vehicle is proposed, which has a device according to the solution proposed here, wherein the support rail is oriented in the x direction and the door leaf of the sliding door of the rail vehicle is connected to the fastening point of the rocker, wherein the device is designed for lifting or lowering the door leaf in the region of the closed position.

Furthermore, a method for sealing a door leaf of a rail vehicle is proposed, wherein, in the step of moving the door leaf in the region of the closed position, the door leaf is moved in the z direction of the rail vehicle by means of a moving device in order to press a sealing element of the door leaf against a mating sealing element of a door frame of the rail vehicle.

Detailed Description

In the following description of advantageous embodiments of the invention, the same or similar reference numbers are used for elements which are shown in different figures and which function similarly, wherein repeated descriptions of these elements are dispensed with.

Fig. 1 shows a view of a rail vehicle 100 with a sliding door 102 according to an embodiment. The sliding door 102 has a device 104 according to the solution presented herein. The sliding door 102 has a single door leaf 106. The door leaf 106 can be moved in the vehicle height direction, i.e. upwards or downwards, by means of the device 104 for sealing. This track height direction may be referred to as the z-direction.

The apparatus 104 has at least one mobile device 112. The displacement device is designed to move the door leaf 106 in the z direction in the region of the closed position of the sliding door 102. Here, the sealing element of the door leaf 106 is pressed against a mating sealing element of a door frame 107 of the rail vehicle 100. The door leaf 106 can be raised or lowered for sealing.

The moving means 112 may be an active member, i.e. an actuator, such as a pneumatic cylinder or an electric motor. The displacement device 112 is then directly actuated according to one embodiment in order to move the door leaf 106 in the z direction. The mobile device 112 may be installed into the sliding door afterwards. For example, the sliding door 102 may already have a receptacle for the mobile device 112.

In one embodiment, the apparatus 104 includes a support rail 108 oriented in the longitudinal direction of the vehicle and a guide rail 110 oriented substantially in the longitudinal direction of the vehicle. The displacement device 112 is designed as a rocker 112 and is mounted movably on the support rail 108 and is connected to the door leaf 106. The rocker 112 is supported on the guide track 110 at least close to the closed position of the door leaf 106 in order to bring about a vertical movement of the door leaf 106 via the rocker 112.

According to one exemplary embodiment, the mounting rail 108 is of generally rectilinear configuration. Alternatively, the support rail 108 may be partially constructed linearly. According to one embodiment, the support rail 108 is of rectilinear design at least in one section forming the guide track.

The device 104 can be referred to as a guide system 104 and is configured to lower the door leaf 106 in the region of the closed position during the closing movement of the sliding door 102 in order to bring the sealing means into contact with the upper and lower edges of the sliding door. In turn, the door leaf 105 is lifted in the region of the closed position when opened, in order to separate the sealing means.

Advantageously, the sliding door 102 can be sealed very well both in the upper region and in the lower region according to the solution described here. No grinding seals which are difficult to adjust are required for this. Sealing of the sliding door 102 is required in order to improve the comfort for the passenger in terms of sound insulation and pressure tightness or also to improve the thermal insulation for low energy consumption.

In the solution proposed here, the door leaf (TFL)106 is lifted or lowered. The raising or lowering may be referred to as movement in the z direction. This function is basically independent of the drive system for driving the door leaf 106 in the x direction and for locking the door leaf 106. By means of the lifting or lowering, the sealing surfaces in the area above and/or below the door leaf 106 are sealed, except for the rear edge and the front edge or the finger protection rubber. The sealing above or below is achieved by pressing the seal against the sealing surfaces or by reducing the distance between the two sealing surfaces from one another. For example, the sealing surfaces can abut against one another, whereby the distance between the sealing surfaces is zero. In principle, the lifting of the door leaf 106 is carried out as close as possible to the closed position of the door leaf 106.

The z-movement of the door leaf 106 is also implemented in one embodiment by active means, such as a servomotor, magnet or cylinder. In another embodiment, the z-movement of the door leaf 106 is realized via a drive in the x-direction and a suitable kinematic mechanism already existing for the push-pull movement. Ideally, the lifting or lowering of the sliding door or the z-lifting is only carried out when the closed position is reached, so that a pure z-movement is achieved without additional x-and y-movements, in order to minimize the grinding displacement of the upper and lower seals as far as possible. The lifting may be achieved, for example, by a lever system 112. Accordingly, the door leaf can be lowered as shown here.

In one exemplary embodiment, the rail vehicle 100 has a swing-out door 102 which is raised or lowered in the z direction in the region of the closed position by a device 104 in order to seal the sealing element.

Fig. 2 shows a view of the device 104 according to an embodiment. The device 104 is substantially the same as the device in fig. 1. In contrast to this, however, the device 104 is designed to move the door leaf 106 in the vehicle height direction, in this embodiment a lift, in the region of the closed position when closed. The pivot point 200 or pivot axis 200 of the pivot lever 112 is rotatably supported in the support roller unit 202. The support roller unit 202 has a single support roller 204 which rolls on the support rail 108 in the longitudinal direction of the vehicle during the opening and closing movement. Here, the rotation shaft 200 corresponds to a rotation shaft supporting the roller 204. The support roller unit 202 can also have a plurality of support rollers 204, wherein the axis of rotation 200 extends, for example, through the center of gravity of the support roller unit 200. The vehicle longitudinal direction may be referred to as the x-direction.

The rocker 112 has a guide arm 206 and a carrier arm 208. The door leaf 106 is suspended on the carrying arm 208 via a tab 210. In other words, the carrying arm 208 has a fixing point 212 for the door leaf 106. A guide roller unit 214 is provided at one end of the guide arm 206. The guide arm 206 receives a torque caused by the weight of the door leaf 106 on the guide rail 110 via the guide roller unit 214. The guide roller unit 214 has a single guide roller 216. The axis of rotation of the guide roller 216 is substantially parallel to the axis of rotation of the support roller 204. The guide roller unit 214 may have a plurality of guide rollers 216.

The guide track 110 is formed by a guide surface 218 of the support rail 108 and a connecting element 220 screwed onto the support rail 108. The connecting element 220 forms a rolling surface for the guide roller 216, which is oriented obliquely to the guide surface 218. When the guide roller 216 rolls onto the connecting link 220, the rocker 112 rotates about its axis of rotation 200 and the door leaf 106 is lifted.

In one embodiment, the guide track 110 is comprised of a guide surface 218 and a recess in the support rail 108. The guide roller 216 then rolls from the guide surface 218 into the recess and the rocker 112 rotates in the opposite direction about the axis of rotation 200, wherein the door leaf 106 is lowered.

When the guide rollers 216 rest against the guide surfaces 218, the carrier arms 208 are oriented substantially horizontally. The guide arms 206 are angled with respect to the carrier arms 208 and are directed obliquely downwards. The carrier arm 208 is approximately half the length of the guide arm 206. This results in a lever ratio in which the guide roller 216 is pressed against the guide track 110 with a weight which is approximately half the weight of the door leaf 106 which acts on the carrying arm 208. Here, approximately one and one half times the gravitational force is applied to the support rollers 204.

In other words, fig. 2 shows the device 104 for lifting the sliding door 106. The device 104 is used, for example, in a sliding door boarding system.

FIG. 3 shows a view of the device 104 with an additional rocker 112, according to an embodiment. The device 104 substantially corresponds to the device in fig. 2. In addition, the device 104 has a further rocker 112, which is of identical construction to the rocker 112 and rolls on the support rail 106 at a distance from the door width of the door leaf 106, spaced apart from the rocker 112 by means of a further support roller 204. In this case, the web 210 extends substantially over the width of the door and is coupled to the two rockers 112. The door leaf 106 is screwed to the tab 210. The further rocker 112 is pivoted in the region of the closed position via a further connecting link 220 provided on the support rail 108.

In other words, fig. 3 shows the mechanism 104 for lifting. With this design, in principle, lowering can also be achieved in the closed position.

For optimization with regard to the smallest possible displacement force or drive force with the highest possible sealing stroke, i.e. the stroke of the door leaf 106 in the z direction, parameters can be taken into account. At least a low degree of release is required in order to avoid abrasion of the seal over the entire displacement or door stroke, i.e. the movement in the x direction. For example, a lever ratio based on the coordinate positions of the rotation point 200, the fixed point 212, and the guide point may be considered. Likewise, the weight of the door leaf 106 may be considered. Furthermore, the sealing forces above and below (N/mm) and the sealing forces acting on the rear edge via the seal and on the finger protection rubber can be taken into account. The maximum possible driving force and the minimum required lift in the z-direction are also parameters. The inclination of the connecting link 220 may also be taken into account. Other parameters are the grinding displacement of the transverse seals above and/or below. The abrasive displacement should be minimal in order to minimize seal wear. Likewise, the desired displacement in the x-direction can be taken into account just before the closed position, at a zero degree inclination of the coupling element. This makes it possible to prevent forces in the opening direction from being generated in the closed position and the locked position of the boarding system, which forces would act counter to the locking. When the roller is in the connection element 220 with an angle greater than zero degrees, a force component in the x-direction is automatically generated which is related to the weight of the door leaf 106 and the connection element angle.

The lifting of the door leaf 106 brings the following advantages: the door leaf 106 is pressed in the opening direction by the weight of the door leaf 106 via the connecting link 220 during a possible emergency operation of the system 104, and therefore a certain gap can be produced between the finger protection rubbers.

Fig. 4 shows a cross-sectional view of the device 104 according to an embodiment. The device 104 substantially corresponds to one of the devices shown in fig. 1 to 3. The support rail 108 and the guide rail 110 are formed in one piece by a plate profile. The support rail 108 has a convex support contour, while the support rollers 204 have a concave roller contour. The support rollers 204 are guided in the vehicle lateral direction or y-direction by a combination of a convex profile and a concave profile. The guide rollers 216 and guide tracks 110 have a flat profile.

Fig. 5 shows a view of the device 104 according to an embodiment. The device 104 substantially corresponds to the device in fig. 4. Here, the carrier arm 208 is oriented in line with gravity. That is, the carrier arm 208 hangs vertically downward. The guide arms 206 are angled here and are partially integrated into the carrier arms 208. The lever arm of the guide arm 206 is about as large as the carrier arm 208.

The guide surface 218 is designed here as a recess in the support rail 108. The inclined rolling surface is configured as an outlet of the recess. When the guide roller 216 is arranged in the region of the guide surface 218, it is substantially unloaded and can be out of contact with the guide surface. When the guide rollers 216 are arranged in the region of the inclined running surface, the carrying arms 208 turn laterally upward together with the door leaf 106.

Fig. 6 shows a view of a lifting movement of a sliding door 102 according to an embodiment. The sliding door 102 is guided by a guiding system according to the solution proposed herein. By means of this guide system, the door leaf 106 of the sliding door 102 performs a substantially vertical movement in the region of the closed position. By this movement, the sealing surface 600 is pressed against the sealing element 602 and the gap 604 between the door leaf 106 and the frame 606 of the sliding door 102 is sealed.

Here, the sealing surface 600 can move together with the door leaf 106 and the sealing element 602 is arranged on a frame 606.

The door leaf 106 is guided in the y direction by a sliding strip 606. The sliding bar 606 is arranged in a cavity (Tasche) and can be moved in this cavity likewise in the z direction. An impact plate profile (trittleistenprofile) 608 is arranged on the outer side of the sliding door 102. The door leaf 106 runs in the gap between the fender profile 608 and the bottom of the rail vehicle 10.

The sealing surface 600 is formed by the lower transverse profile 610 of the door leaf 106. A profile 612 is likewise provided as a sealing profile on the rear edge of the door leaf.

In other words, fig. 6 shows an example in which the door leaf 106 is sealed below. Here, the door leaf 106 is shown for the design of the door leaf 106 lifted once into the open position and lifted once into the closed position. The seal 602 is formed on the lower side of the door frame, i.e. not on the door leaf 106. Conversely, the seal 602 may also be provided on the door leaf 106. The sealing surface 600 is located on the door leaf 106. The lower guide 606 is here conventionally designed, wherein, despite the lift in the z direction, there is still sufficient covering of the guide system.

Fig. 7 shows a view of a sealing element 700 for a sliding door 102 according to an embodiment. The sealing element 700 is arranged on the rear edge of the door leaf 106 and can be moved together with the door leaf 106 in the x-direction. The sealing element 700 seals against a sealing surface 702 which is provided on the door frame 107 of the sliding door 102. The sealing face 702 is formed by a seal horn (dichtwinkkel). The sealing element 700 is designed as a deformable lip.

In other words, fig. 7 shows an example of sealing of the rear edge of the door leaf. The seal 700 may in turn be positioned on either the door frame side or the door leaf side. For the transition to the upper and lower transverse seals, corresponding profiles can be used in order to minimize the formation of leakage surfaces at the transition.

Fig. 8 shows a detailed view of a rail vehicle 100 with a device 104 according to an embodiment. The device 104 here corresponds essentially to one of the devices in fig. 1 to 5. The device 104 is integrated into a door frame 107 of the rail vehicle 100. The support rail 108 is here fixedly connected to the door frame 107. The rocker 112 is guided on the support rail 108 and is connected to the door leaf 106. An upper sealing surface 800 is provided on the door leaf 106, and an upper sealing element 802 is provided on the door frame 107. By a vertical movement of the door leaf 106 in the region of the closed position, the sealing surface 800 presses against the sealing element 802 and seals the gap between the door leaf 106 and the door frame 107.

The upper sealing surface 800 is here a component of the upper transverse profile of the door leaf 106.

In other words, fig. 8 shows one example of the portal 106 sealing above. The open position is shown here. The seal 802 is configured on the door frame side and the sealing surface 800 is located on the door leaf 106.

The seal 802 itself may be mounted on the mast 107 of the vehicle 100 as a completely surrounding seal carrier. This results in a very good transition between the longitudinal seal and the transverse seal and in the transition of the door leaves. The door leaf 106 is the sealing surface 800 and does not require a receptacle for a seal, apart from a finger-protecting rubber.

If this solution is not possible, the seal 802 may be placed on the door leaf 106, wherein the sealing surface 800 is then placed on the door frame 107. By lifting the door seal 802, the seal or the forming element in the transition between the longitudinal seal and the transverse seal can be configured such that no leakage surface is present in the closed position.

Fig. 9 shows a view of a sealing element 602 for a sliding door 102 according to an embodiment. The sealing element 602 may be used, for example, in place of the sealing element in fig. 6. Here, the sealing element 602 is fixed to the door leaf 106. The seal face 600 is fixed to the vehicle. The sealing element 602 is configured as a deformable lip as shown in fig. 7. When the door leaf is lifted via the guiding system, the sealing element 602 is in contact with the sealing surface 600 and seals the gap at the bottom.

Fig. 10 shows a view of the device 104 according to an embodiment. The device 104 corresponds substantially to the device in fig. 2 and 3. In contrast, the rocker 112 has an upwardly directed projection 1000 with a pivot point 200. The pivot point 200 corresponds here to the pivot point of the support roller 204. The center of gravity of the rocker 112 is disposed below the pivot point 200, whereby the rocker 112 has a high self-stability. The fastening point 212 is arranged here substantially at a height from the guide roller 216.

The connecting element 220 is connected to the mounting rail 108 in a stationary manner. For example, the connecting link 220 is welded or glued to the support rail 108. The connecting link 220 has an inclined portion 1002 oriented obliquely to the guide surface 218 and has a stop surface 1004 oriented parallel to the guide surface 218. The guide rollers 216 are disposed on the stop surface 1004 in the closed position. From the beginning of the inclined portion 1002 until the closed position, the connecting link 220 has a length of less than 80 mm.

During the closing movement, the guide roller 216 rolls downward via the inclined portion 1002. Thereby, the fixing point 212 is lifted at the opposite side of the rotation point 200. The fixed point 212 is lifted less than 15 mm.

Fig. 11 shows a view of coupled device 104 according to an embodiment. The device 104 here corresponds essentially to the device in fig. 10. In contrast to this, the pivot point 200 is essentially located here on the connecting line between the fastening point 212 and the guide roller 216. The rotation point 200 is rotatably supported in the coupling member 1100. The coupling member 1100 couples the rotation point 200 with the supporting roller unit 202. By means of the coupling 1100, the trajectory of the fixing point 212 is oriented substantially transversely to the support rail 108.

Fig. 12 shows a flow chart of a method 1200 for sealing a door leaf of a rail vehicle, wherein, in a step 1204 of movement in the region of the closed position of the door leaf, the door leaf is moved in the z-direction of the rail vehicle with a moving device in order to press the sealing element of the door leaf against a mating sealing element of a door frame of the rail vehicle. According to one embodiment, step 1204 is performed independently of the further closing movement of the door leaf.

According to another embodiment, step 1204 is performed together with or in combination with a further closing movement of the door leaf. For this purpose, the method 1200 for example also has a guiding step 1202 in which the door leaf of the sliding door is guided from the open position in the closing direction into the region of the closed position by means of a guiding system according to the solution proposed here. Between the region of the open position and the closed position, at least one sealing surface of the sliding door oriented in the closing direction and at least one sealing element of the sliding door oriented in the closing direction are guided without contact by the guide system. In a lifting or lowering step 1204, the door leaf is lifted or lowered in the region of the closed position by means of a guide system in order to bring the sealing surface into contact with the sealing element.

Before or during the opening of the door leaf, step 1204 can be carried out again, wherein the door leaf is then moved in the opposite z-direction compared to the movement during the closing process in order to release the sealing element of the door leaf from the mating sealing element of the door frame. Accordingly, step 1202 can be carried out again during opening, wherein the door leaf likewise moves in the opposite direction compared to the movement during the closing process.

Fig. 13 shows a view of an apparatus 104 for sealing at least one door leaf 106 of a vehicle according to an embodiment. The vehicle may be a vehicle as described with reference to fig. 1, for example. The device 104 includes a rocker 1350 having a first guide arm 1351 and a second guide arm 1352. The rocker 1350 is, for example, shaped as a U or V. The

guide arms

1351, 1352 form legs of the rocker 1350. In the region of the connection of the

guide arms

1351, 1352, the rocker 1350 has a pivot point 200 via which the rocker 1350 can be pivotably connected to the door leaf 106 and, in the view shown in fig. 13, to the door leaf. According to this exemplary embodiment, rocker 1350 has a round through-opening in the region of pivot point 200. For example, a shaft or shaft coupled to the door leaf 106 can be guided through the through-opening.

The first guiding arm 1351 has a first fixing point 1355 at its free end, while the second guiding arm 1352 has a second fixing point 1356 at its free end. According to this embodiment, the

guide arms

1351, 1352 each have a through-opening in the region of the fastening points 1355, 1356, for example for receiving a shaft or axle. According to the illustrated embodiment, a first supporting roller 1360 of a first supporting roller unit 1361 is fixed on the first fixing point 1355 on the first guide arm 1351, and at least one second supporting roller 1363 of a second supporting roller unit 1364 is fixed on the second guide arm 1352 on the second fixing point 1356. In addition to the

support rollers

1360, 1363, the

support roller units

1361, 1364 can also comprise, for example, shafts for fastening the

support rollers

1360, 1363 to the fastening points 1355, 1356.

According to one embodiment, rocker 1350 is configured as a flat plate extending along the x-z plane. Alternatively, rocker 1350 may also have at least one bend. The fastening points 1355, 1356 are arranged offset to one another in the x direction. The rotation point 200 is arranged between the fixing points 1355, 1366 with reference to the x-direction. When the guide arms 1355, 1352-unlike the embodiment shown in fig. 13-extend parallel to one another, the pivot point 200 can be arranged on the connecting line connecting the

respective fastening points

1355, 1356. If the

guide arms

1351, 1352 are angled relative to one another as shown in fig. 13, the pivot point can then be offset from the fastening points 1355, 1356 in the z-direction, in this case, for example, in the direction of the lower edge of the door leaf 106.

Fig. 13 shows a support rail 108 with a guide surface 218 and a connecting link 220 in a vehicle or a vehicle door frame. The guide surface 218 is a track extending in the x-direction. The

support rollers

1360, 1363 are shaped so as to be able to roll along the guide surface 218. The connecting element 220 is formed according to this exemplary embodiment as a plate-shaped element, which is fastened to the mounting rail 108. The edge of the connecting link 220 is shaped as an inclined portion 1002 oriented obliquely to the guide surface 218 and a stop surface 1004 adjoining the inclined portion 1002 and oriented parallel to the guide surface 218. The inclined portion 1002 starts at the height of the guide surface 218. According to this exemplary embodiment, the second support roller unit 1364 has a single second support roller 1363 which is shaped so as to roll over the elevation of the connecting element 220 not further on the guide surface 218, but rather on the inclined portion 1002 and the stop surface 1004. The guide surface 218 together with the inclined portion 1002 and the stop surface 1004 thus form a guide track for guiding the supporting

rollers

1360, 1363 during the closing movement as well as the opening movement of the door leaf 106. Here, the first supporting roller 1360, according to one embodiment, rolls only over a section of the guide track formed by the guide surface 218.

According to one embodiment, the distance in the x-direction between the first fixed point 1355 and the rotation point 200 is a value a, and the distance in the x-direction between the second fixed point 1356 and the rotation point 200 is a value b. The value a is illustratively larger than, e.g., at least twice the value b. In the illustrated position of the device 104, the force F1 acts on the first fixed point 1355, the force F2 acts on the second fixed point 1356 and the force F3 acts downward on the rotation point 200.

The door leaf weight force F3 at the connection point of the door leaf 106 lies between the first supporting roller (force F1) and the second supporting roller 1363. The second support roller 1363 is moved in the region of the closed position of the door leaf 106 onto the connecting link 220 formed as a wedge. The first support roller 1360 moves according to this embodiment only on the guide surface 218 shaped as a running surface. The second support roller 1363, in principle, also rolls on the guide surface 218, but moves shortly before the closed position onto the inclined portion 1002 of the connecting link 220 and thus controls the vertical movement of the door leaf 106.

For each door leaf 106, at least on the front and rear edges of the door leaf 106, a roller pair of supporting

rollers

1360, 1363 is formed. Thus, the device 104 has according to one embodiment a further rocker with a further bearing roller and a further connecting link. In order to integrate the arrangement as space-saving as possible in terms of space requirements in the longitudinal direction (x direction) in terms of the required rail length of the support rail 108, a certain degree of overlap is possible. Such an overlap enables the connecting link 220 of the second support roller 1363 on the rear edge of the door leaf 106 to be moved on the front edge, as can be seen in fig. 14.

The embodiment shown in fig. 13 and 14 has the advantage that the force F3, i.e. the weight of the door leaf 106, is distributed over the two supporting

rollers

1360, 1363, also referred to as running rollers. This makes it possible to avoid a higher load on the first supporting roller 1360 than the load which is caused by the door leaf 106 and corresponds to the force F3 acting on the pivot point 200.

Fig. 14 shows a cross-sectional view of a device 104 for sealing at least one door leaf according to an embodiment. A cross-sectional view of the device 104 shown with the aid of fig. 13 can be mentioned in this case. The rocker is not shown here.

Support rollers

1360, 1363 are shown, wherein a first support roller 1360 rests on the guide surface 218 of the support rail 108 and a second support roller 1363 rests on the stop surface 1004 of the connecting link 220.

The first supporting roller 1360 has a guide groove 1480 for guiding the first supporting roller 1360 along the guide surface 218. The second supporting roller 1363 has a further guide groove 1483 for guiding the second supporting roller 1363 along the guide surface 218 and has a connecting link surface 1485 arranged next to the guide groove 1483 for guiding the second supporting roller 1363 along the connecting link 220. The connecting ring pitch surface 1485 is formed by a cylindrical section of the second support roller 1363 according to this embodiment.

The guide surface 218 is formed according to this exemplary embodiment by a U-shaped section of the mounting rail 108.

Fig. 15 shows a cross-sectional view of a device 104 for sealing at least one door leaf according to an embodiment. This device 104 corresponds to the exemplary embodiment described with reference to fig. 14, with the difference that the second support roller unit is of multi-part design, in this case for example of two-part design. According to this embodiment, the second bearing roller described with the aid of fig. 14 is divided in order to minimize sliding and therefore also wear. Thus, the second support roller unit includes the second support roller 1563 and the additional second support roller 1564. The second support roller 1563 has another guide groove 1483 for guiding the second support roller unit along the guide surface 218. The further second support roller 1564 has a connecting ring pitch surface 1485 for guiding the second support roller unit along the connecting link 200. The two

second support rollers

1563, 1564 have a common axis according to this embodiment.

If an embodiment includes an "and/or" association between a first feature and a second feature, this should be understood as meaning that the embodiment has not only the first feature but also the second feature according to one embodiment and only the first feature or only the second feature according to another embodiment.
